astron.
the world’s fi rst
gps solar watch.
In 2012 we made history with Astron, the world’s first GPS solar watch.
Using just the power of light, Astron adjusts to every time zone on earth at the touch of a button.
In 2014 we took Astron even further, introducing a full-function GPS solar chronograph.
Now with dual time display, Astron is simply the world’s finest GPS solar watch.*If there are changes in the region / time zone, manual time zone selection may be required.seiko.com.au
